To all whom "it may concern: y

Be it known that I, CLARENCE H. HUNs- BERGER, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Wire Guards for Electric Lamps, of which the following is aspecification.

This invention relatesto a wireguard for inclosing electric light bulbs and other similar fragile articles, and primarily to the means for detachably fastening the wire guard to the bulb or other article i The object ofthe invention is to produce a strong, durable and comparatively cheap device of this character, which may be very readily attached toand detached from the electric light bulb or other article, and which when in place, surrounds and protects said bulb or other article from injury.

The invention also relates to certain details of construction of thewire guard and the locking means therefor, which will be hereinafter described ence being had to the ings in which,

Figure l is a wireguard attached to and inclosing an incandescent electric light bulb and a screw socket for said bulb, and a portion of the covered electric conducting wire also being shown. Fig; 2 is a detached top plan view of the wire guard. Fig. ,3 is a section throughthe upper ring to illustrate one of the members of the clasp or look in side elevation.-

1 In referring to the drawing in detail, like numerals designate llkQPZLIl/S;

Theimproved wire guard consists, of an upper circular end ring 1, a-pluralityof ribs 2 having their upperr ends bent around the wire ring 1, and. a spirally woundwire which is fastened at its upper end to the upper circular ring 1 and winds spirally downward therefrom,,being connected at its contact points by solder oriother suitable means to the ribs 2. upper ends attached at equal intervals aroundthe circular upper ring 1, and extend downwardly therefrom, with their lowerends curving inwardly into, contact at the pointt. a a r I and extend across to the and claimed, referaccompanying drawperspective view of the in Fig. 3, and

The ribs 2have their This improved guard is adapted to loosely surround and inclose an electric light bulb or similar fragile article, and thereby protect it from injury. y

Referring to Fig. l, a conventional form of electric. light bulb 5 is shown therein, which is-provided with a supporting socket 6 to which saidbulb is detachably attached. The socket 6 is connected to the end of a covered electric wire 7 in the usual well known manner. e

It will be noted that the improved guard is entirely out of contact with the bulb, means being provided for clasping or looking the wire guard to the socket;

The device for detachably fastening the wire guard to the lamp socket consists of two opposed members which are loosely secured atone end to one side of the ring 1, opposite side of the ring, being sprung or snapped into interlocking engagement at said opposite end tofirmly clasp or embrace the lamp socket between them. One of the members of the locking device has an eye-portion 8 at one end which loosely encircles the ring 1, and areturn bent portion 9 at its opposite end which fits loosely around the ring 1 on the side opposite the eye-portion 8, as shown an intermediate curved portion 10 which fits partially around the lamp socket when in clasping position, relatively to the same. The other member of the device has a similareye-portion 11 at one end, whichalso loosely encircles the ring 1, laterally bent. orhook portion 12 atthe opposite end which is adapted to be sprung or snapped upon the end portion 9 of the first-mentioned member, and an intermediate curved portion 13 which curves oppositely to the curved portion 10 of the first-mentioned member, and is adapted to fit partially around the lamp socket opposite said portion 10. y

The members of this locking device are preferably made of suitable springwire.

The upperend of the spiral wire 3 is looped around the upper ring ,1, forming a circular enlargement or shoulder ,14 around the same, which-is located fairly close to the eye 15 of one of the ribs2, as shown in Fig. 2.

said bulb within the The eyes 8 and 11 of the two members loosely encircle the ring 1, and are located on said ring between the shoulders 14 and 15, and are limited in their circumferential movement on said ring 1 by the said shoulders 14 and 15, as shown in Figs. 1 and 2.

The bent or hook portion 12 at one end of one of the members, is not only bent laterally to form a hook, as previously de: scribed, but it is also bent downward and then back, as shown at 16 to form a return bend.

The object of this construction is not only to lock the two members together in their clasping position, but also to provide a double lock between the parts of which the ring loosely fits to lock the members to the ring 1 against vertical movement. This will be easily understood by referring to Fig. 1.

To center the wire guard with respect to the incandescent light bulb, a plurality of diagonally extending Wires 17 are fastened at their upper ends to the ring 1, at equal intervals around the circumference of said ring and extending diagonally downward toward each other, gradually converging until they reach the center point 4 at the lower end of the guard to which they are fastened, as shown in Fig. 1. These wires are made of light spring metal and are straight, and are adapted to contact with the surface of the light bulb and thereby center the guard with respect to the bulb, and also to support guard with a yielding or spring tension.

The main advantages of this improved guard .reside in the novel means for detachably fastening the same to the socket of the lamp, the strong, simple and cheap construction of the same, ing and supporting the guard with respect to the lamp bulb.

I claim:

1. A wire guard for lamp bulbs consisting of a wire body adapted to loosely inclose a lamp bulb and having an end ring and a multi-member locking device adapted to be sprung or snapped about the socket of the lamp bulb and having those portions of its members at one end thereof loosely attached to one side of the end ring and the opposite end portions of said members being adapted to be sprung into interlocking engagement with each other and one of said members being also adapted to be locked to the opposite side of the end ring against vertical movement.

2. A wire guard for lamp bulbs consisting of a wire body adapted to inclose a lamp bulb and having an end ring and a locking device attached to the end ring of the wire body and adapted to be sprung inclasping position about the socket of the lamp bulb,

and the means for center said locking device consisting of two members, each having an eyeat one end loosely encircling the end ring at one sidethereof, a return bend portion at the opposite end' adapted to be sprung into locking engagement with the bent portion of the other member and around the end ring, and oppositely curved intermediate portions between which the socket of the lamp bulb is clamped. V 1

3.
